Barring all the philosophical talks- I'll just tell you what I do- I TREAT myself :) :) Go out, scream your lungs out, wear your best smiles- isn't it enough 'you' are 'happy'?! :) That is what I do :)

oh it happens to me all the time. i just spread my happiness to all those around, even if they aren't looking/listening. sooner or later they'll want to become your friends so that they can share your happiness :)

of you're talking about a more intimate sharing of happiness than friends can afford, i guess i'm as lost as you are...i've been battling that problem on and off for most of my adult life :)
